Question

what is hibernation? how does it help the polar bear survive in the polar region?​

Answer 1

Answer:

Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food.

In order to hibernate, polar bears not only need to prepare a den, but also their bodies. Polar bears have the ability to increase or decrease their metabolic rate (how much energy they use), so they can survive through their hibernation without running out of energy.

Answer 2

Answer:

Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. Two coats of fur and a thick layer of blubber help insulate the polar bear's body from the cold, keeping its temperature at an even 37° C (98.6° F).
